I am setting up a basic donation system and need to send a confirmation email to the client but cannot get the buyer postal address to show on return_url page of the website, or to show in the email to send to the client. The custom values for the taxpayer yes/no radio selects won't follow through either in the email. I am using a custom form on our website with fields to fill in the donation amount, name, address and if they pay tax (simple radio select.) Not sure if I'm using it right but I have both IPN and PDT settings on the site site and setup within the PayPal account.
Donation Form:

At the moment all I need to get working is the address to show on the email, return_url page and PayPal website (currently says Postal Address: Not Specified.)
Are you entering in an address when testing? Try passing over the variable "no_shipping" and setting the value to "2", and see if this makes a difference. Also PayPal will not pass back variables/values that are not valid PayPal variables, meaning you would not be able to make up your own variables and pass them over.
